After a little bit of debugging, I have discovered that when there are QueryString parameters, passed such as /images/pic1.jpg?thumb=1 the ProcessRequest method of the Handler doesn't get called.
I added a line to the ProcessRequest medhod to write a log to a text file for each iteration of the method. I also added log statements to various places in the code. After browsing a couple of pages, I realize that every entry in the log is an entry for which there is no querystring. Below is the code I put in the handler : > public class ImageHandler:IHttpHandler > { > > HttpResponse Response; > HttpRequest Request; > HttpServerUtility Server; > > #region IHttpHandler Members > > public void ProcessRequest(HttpContext context) > { > > //Set global context objects > Server = context.Server; > Response = context.Response; > Request = context.Request; > > //Do the image stuff > > ///DEBUG > Log("Beginning image output [QS=" + > Request.QueryString.Count.ToString() + "] = " + Request.RawUrl); > ///DEBUG > > RequestImage(); > > } > public bool IsReusable > { > get{ return true; > } > > [... rest of the handler code ...] > And the Logger. > //debugging logger > public static void Log (String logMessage) > { > > StreamWriter w = > File.AppendText("/home/gary/www/mysite/www/images/hih_cache/hih_log.txt"); > w.Write("\r\nLog Entry : "); > w.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(), > DateTime.Now.ToLongDateString()); > w.WriteLine(" :{0}", logMessage); > w.WriteLine ("-------------------------------"); > // Update the underlying file. > w.Flush(); > w.Close(); > } Records in the log file were like : > Log Entry : 10:02:52 AM Monday, June 20, 2005 > :Beginning image output [QS=0] = /images/banner_c1.jpg > ------------------------------- Anyone else having this kinda fun?
